Thread starter Crabber Start date Jan 19, Crabber New Member Jan 19, Hi, I have a combination type Sharp microwave however the microwave function has failed. I’m new to electronics but have hfr elsewhere on this forum about a popular fault with 2x62h microwaves being a strange protective ‘diode’ that is positioned across the terminals of the large capacitor together with a second tradionally labelled diode HVR-1X7 which is connected positive side to one side of the capacitor with the negative side to earth.

The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH. The tradional diode has been gvr and appears to work correctly i.

I have purchased and fitted a replacement 2XH diode but the microwave still doesn’t work.

Sharp Combi Microwave and Strange Diode

This diode however gives different test results to the original part which behaves under test as a tradional diode i. The replacement ‘diode’ shows How do these diodes work and any suggestions as hgr the problem with my microwave?

I’m a bit bemused why you’re checking it with 12V – as it reads However, it’s NOT a functioning part of a microwave, and the oven will work fine without it. Hi Nigel and thank you for your reply. Perhaps I didn’t make myself hhvr enough.

2XH – HVR-2XH –

The HV rectifier does not appear to have failed as it has 7. The new protective ‘diode’ appears to work fine as it will not conduct in either direction as the symbol printed upon it would suggest yet the original part does conduct in one direction with 12v I know that it may work fine without it but not necessarily if it is fitted and faulty.

2×062 note your 14th November response to a similar query ” It’s a special diode, created this 602 specific purpose – no idea how it works, and care even less ” I’ll assume that you still don’t know and hr we should both steer clear of microwaves!!

Has anyone else any ideas? I think I have found the answer to my question and one that has been raised on this forum previously. From a posting by Carl Willis who has posted the below on fusor. This kind of component is effectively two diodes in series, one with a high reverse breakdown voltage rating hgr the other with a much lower rating.

Electronic components HVR-062[M]=2X062H

It is placed in parallel with the HV capacitor in the usual level-shifted magnetron power supply which uses a separate rectifier in series with the capacitor. Its purpose in that configuration is to allow the capacitor to charge to a high voltage of the correct polarity only negative at the magnetron cathodewhich is blocked by the high-breakdown diode in the back-to-back arrangement.

If the capacitor experiences high voltage of the opposite polarity, the weaker diode in the pair fails. I don’t know precisely what condition is being protected against, but my guess is that a hhvr reactive current circulating through the transformer-capacitor pursuant to a failed main rectifier or gassed-out maggie could cause one or both of these components to not “go gentle into that good night.

Or the transformer secondary could hvf down before the core thermal protector opens, ruining the component with the highest commodity value. Engineering of a cheap Chinese appliance is all about pushing the envelope and trimming the margins of safe failure. In any case, I suspect the “protection diode” is only designed to carry current in the permanently-failed state, making it not worth much to you.

In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary hvt. I knew the answer would be out there somewhere. You must log in or 2×062 to reply here.
